● The airlock has a secret code made of shapes. Guess it before the oxygen runs out.
● Tap shapes to fill the glowing row, then press LOCK.
● The lock always tells the truth: LOCKED = right shape in the right place. LOOSE = right shape, wrong place.
● It never says which ones. That is your job — every old guess stays on the board so you can work it out.
● Crack it in few guesses for a bigger score. Run out of guesses and the airlock breaches — three breaches ends the mission.
● Keyboard: number keys place a shape, arrows move, Backspace undoes, Enter locks it in.
Relaxed gives you four times the time to answer — start here. Turn it up when the game starts feeling easy.
A lost lock holds for a moment with the real code lit, and that same code comes back a few locks later. Off makes it a quiz instead of a lesson.

“Sound guesses” are guesses that could still have been the code, given the clues already on the board. A guess that contradicts an earlier clue can never be right — it is a wasted turn.
